GRUBBER.

Specification of Letters Patent.

Application filed October 2, 1914. Serial No. 864,665.

l vices, and it has for its object to produce an implement of simple andinexpensive construction by means of whlch grubs may be quickly andeffectively extracted from the ground with little manual exertion.

A further object of the invention is to produce a device of this classadapted to engage the stem of the plant that is to be extracted and toafford a suitable hold thereon to enable the roots to be extracted fromthe ground without danger of cutting or breaking the stem.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying "drawing has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may be resorted to when desired.

In the drawing,Figure 1 is a plan view of the improved grubber showingthat side which is held upward when the device is in use. Fig. 2 is aview of the opposite side of the device. Fig. 3 is a transverse sectional view taken on the line 33 in Fig. 1. Fig. 4 is a longitudinalsectional detail view taken on the line M in Fig. 3.

Corresponding parts in the several figures are denoted by likecharacters of reference.

A clip 15 secured on a wooden handle 16 a short distance from one endthereof is provided with laterally extending arms 17 between which ablade 18 of ieavy tool steel is mounted in an inclined position by meansof a bolt 19, one end of said blade being also attached directly to thehandle by means of a bolt 20. The outer end of the blade will thus bespaced from the handle by a wedgeshaped recess, and said outer endportion of the blade is beveled to produce a sharp edge 21, the beveledor inclined face being also provided with struck up teeth 22. The arms17 may be provided with auxiliary apertures 28 for the passage of thebolt 19 in order that adjustment may be made to vary the width of thewedge-shaped recess 24: be-

tween the outer end of the blade and the adjacent portion of the handle.An auxiliary blade 25 is secured on the handle adjacent to the clip 15,said auxiliary blade consisting of a plate curved to the contour of thehandle and having an out-turned sharp-edged flange 26 facing the edge ofthe blade 18.

In practice, the operator grasping the handle manipulates the device tointroduce the stem of the grub that is to be extracted between thesharp-edged portion of the blade 18 and the proximate portion of thehandle. By using the latter as a lever, the grub may now be loosened orpartly extracted from the ground, after which by a twisting motion ofthe handle, the stem of the grub will be engaged by the flange 26 of theauxiliary blade which prevents slipping while the grub is beingcompletely extracted.

This device which is simple in construction and quite inexpensive willbe found thoroughly effective for the purposes for which it is provided.7

Having thus describedthe invention, what is claimed as new, is

1. A grubbing device comprising a handle, a blade secured thereon in aninclined position to produce a wedge-shaped recess between said bladeand handle, and an auxiliary blade secured on the handle and having aflange portion facing the first mentioned blade.

2. A grubbing device comprising a handle, a clip secured thereon andhaving laterally extending arms, a blade secured between said arms in aninclined, position with respect to the handle, said blade having abeveled sharp-edged portion provided with struck-up teeth, and anauxiliary blade consisting of a plate secured on the handleand having asharp-edged flange facing the edged portion of the first mentionedblade.

In testimony whereof I aflix my signature in presence of two witnesses.
